New Spinning Drone Hides In Plain Sight

2 août 2026 à 22:09
To design invisible drones, researchers have tried camouflage, transparent materials and light-bending optical systems. But engineers at Northwestern University used "motion blur," which an announcement from the school notes is the effect that makes fast-spinning fans seem to disappear. "The drone spins up to 25 times per second, which is too fast for the human eye to see clearly. While it isn't completely invisible, it morphs into a ghostly smudge that seamlessly blends into the background... " To design the drone, the Northwestern team first used a computational model to generate roughly 20,000 drone configurations capable of stable flight. Then, they used artificial intelligence (AI) and optimization algorithms to repeatedly rearrange the drones' major components, including a motor, propeller, circuit board, counterweight and batteries. After sifting through many different configurations, the algorithms determined the ideal placement of the drone's components to minimize its visibility from virtually every viewing angle while allowing for stable flight. After selecting promising candidates, the engineers simulated each drone spinning in flight and overlaid those images a hundred real-world backgrounds. Then, they used a perception model that approximates human vision to determine how noticeable each design appeared. Designs that blended into their surroundings received lower visibility scores. The team selected the 500 lowest-scoring designs and applied the optimization algorithm, which repeatedly adjusted the positions of components to further minimize those scores. "The design process was fully automated," [said Northwestern's associate CS professor Michael Rubenstein, who led the work]. "Then, when we were confident that a drone met all our criteria, we built it." They've named the drone "Phantom Twist"," and plan to design future iterations with more transparent materials or quieter propulsion to make it even less noticeable. The Northwestern team presented the work on July 16 at Robotics: Science and Systems 2026 in Sydney, Australia... Thanks to long-time Slashdot reader fahrbot-bot for sharing the news.

Is There a Way to Promote Open Document Formats Instead of 'MS Office' Format?

2 août 2026 à 21:09
The Register looks at exactly why "It is practically impossible to move any non-trivial Word document out of MS Office to a non-MS suite and back again without it being more trouble than it's worth." OOXML, developed by Microsoft and first standardized by Ecma in 2006, became the ISO/IEC 29500 standard in 2008 after a grueling and adversarial process. Microsoft pursued standardization because it has always been a standards-led organization dedicated to maximizing the options for its customers. Or because it had to at gunpoint, while vowing silently to follow the letter of the law but stymie its intent. You decide... The Document Foundation (TDF) which spends its days worrying about such things, reports that Microsoft has effectively broken the standard by sticking with a transitional version as its default rather than the cleaner Strict variant. The result is that what Microsoft software renders is what Microsoft wants to render, despite nominal compliance... What we need is a test suite that can take any OOXML engine and test its compliance against what Microsoft is actually doing. That means the tooling wrapped around the spec has to account for proprietary dependencies that get smuggled in, such as fonts. It also means actively and continuously tracking the ground truth of Microsoft's evolving products and services. It doesn't need to be perfect, but it absolutely needs to be good enough. Compliant engines have to become good enough for a critical mass of users to coalesce around them. In an earlier article The Document Foundation reminded all software users that they have a choice. "When an institution sends a letter formatted with a proprietary font, embedded in a proprietary format, produced by proprietary software, it is not communicating information but perpetuating a dependency." "Digital sovereignty begins with the recognition that this is a choice: the file format is a choice, the font on the page is a choice, and the software is a choice."

Steam On Linux Use Back Above 4% In July

2 août 2026 à 19:34
Valve just published the Steam Survey results for July 2026, reports Phoronix, "and they point to a small uptick in Linux gaming use." Back in March Steam on Linux hit a record high of 5.33%, dropped to 4.52% in April, landed at 3.99% in May, and then in June was at 3.69%. The just-published numbers for July put Steam on Linux use at 4.01%, as an improvement over the prior two months but still well off the percentage highs of March and April... The July data puts SteamOS Holo as powering around 22% of Steam on Linux gaming systems. That's also with the Steam Machine now shipping, in addition to the Steam Deck.

Group of Teen Hikers Relied on Google Maps. It Was a Disaster.

2 août 2026 à 17:34
"When a group of teenagers set out to hike British Columbia's famed Howe Sound Crest Trail in early July, Google Maps suggested the trek would take about five hours," reports SFGate. "Instead, the hike stretched deep into the night, leaving the group exhausted, dehydrated, injured and in need of a helicopter rescue..." Although the approximately 18-mile route with a 6,000-foot elevation gain can be completed by experienced trail runners in a day, search and rescue officials generally recommend hikers treat it as a two-day backpacking trip. The teenagers, all 17 years old, believed Google Maps' estimate that the route would take about five hours. The printed directions they were carrying, which were shared publicly by Lions Bay Search and Rescue, gave simple instructions for two legs of the trail, but didn't account for the terrain or elevation. "[Google Maps] is calculating the time that you're walking a straight road on pavement," [said Maria Masiar, training officer and search manager with Lions Bay Search and Rescue]. "When you get into outdoor terrain, that no longer holds true." Expecting only a short outing, each hiker carried about half a liter of water and limited food. There are no reliable water sources along the trail, meaning hikers must carry enough supplies for the entire route. As the group climbed, they began suffering from dehydration and muscle cramps but continued onward despite falling dramatically behind schedule. Eventually, the group made the decision to turn back and abandon making it to the end of the trail — and as the sun began to set and the group started to descend, fatigue took its toll. According to Masiar, members of the group had already stumbled and fallen several times while trying to race the coming dark, and only one hiker had a headlamp. Eventually, another hiker slipped about 10 feet off a boulder, injuring his tailbone badly enough that he could no longer continue. Search and rescue crews responded, ultimately evacuating him by helicopter.

Does Eating Less Protein Produce Healthier Aging and Metabolism?

2 août 2026 à 16:34
"A major scientific review is challenging the idea that more protein is always better," reports ABC News: The review, led by pathologist and biomedical researcher Dudley Lamming and published in the journal Cell Press Blue, examined more than 350 studies involving humans, mice, insects, yeast, and other organisms. The review found that eating less protein, or less of certain amino acids that make up protein, may turn on body processes linked to healthier aging, as well as metabolism, the process by which the body turns food and drinks into energy... For adults who already get enough, eating more protein may offer little benefit, while some research suggests that eating less protein could support healthier aging... Lamming reviewed the effect of reducing protein in many body processes. One of the processes involves a hormone called FGF21. "There's an increase in a hormone called FGF21 that promotes energy expenditure [when protein intake is reduced]," Lamming said. "It essentially increases thermogenesis in your adipose tissue, so you don't just store fat, but actually burn it as fuel." This may help explain why some studies connect lower-protein diets with less body fat, better blood sugar control and a healthier metabolism. Eating less protein may also affect signals that tell cells when to grow, repair damage or recycle old cell parts. These jobs may play a role in aging. However, protein restriction is not the same as protein deficiency. The goal is not to deprive the body of an essential nutrient. Instead, the research raises the possibility that avoiding unnecessary excess could benefit some people who already consume enough... Before reaching for another high-protein product, a better question may be: How much protein does my body actually need?

In a First, 'Super-Earth' Planet Shows It Could Have an Atmosphere

2 août 2026 à 15:34
"Scientists say they have detected promising signs that a planet orbiting a star 49 light-years from Earth could have an atmosphere," reports CNN, "making it potentially suitable for life." Called LHS 1140b, the object is about five times the mass of our planet, or a "super-Earth." This planet orbits around its star in the "Goldilocks zone," also known as the habitable zone, meaning its surface temperature is not too hot or too cold for liquid water to exist... "It appears to be consistent with Earth, meaning it might have an iron core and a silicate mantle, plus some sort of low-density component, which is probably a combination of water and, now we know, an atmosphere," [said Collin Cherubim, a planetary scientist and lead author of a paper on the finding, published July 16 in the journal Science]... If further observations confirm the findings, LHS 1140b would mark the first discovery of an atmosphere on a rocky planet in the habitable zone of another star... There is no evidence of life or a life-supporting atmosphere on LHS 1140b now, but Cherubim said he believes it's a formidable candidate for potential signatures of extraterrestrial life. "I think it's the best place to look for life outside the solar system at this point," he said. "It's mostly rocky, it's at the right temperature to support liquid water on the surface, and it has an atmosphere — those are the three key ingredients we look for..." Confirming the existence of an atmosphere on a rocky planet orbiting a red dwarf would be particularly exciting, Cherubim said, because the possibility of that happening is an open question in astronomy. "Can rocky planets have atmospheres around red dwarfs? This is the first bona fide yes," he said. "It's kind of a sigh of relief for a lot of us. But the jury's still out. Maybe this is a weird planet, and it's an oddball, or maybe it's the first of many. We don't know yet." Now "The James Webb Space Telescope is going to look at it," Cherubim told CNN, and "Hubble's going to look at it. Basically, everybody who can see it is going to be training their eyes on it." Michaël Gillon, research director of the Astrobiology Research Unit at Belgium's University of Liège warned CNN that no definitive proof exists that LHS 1140b possesses a substantial atmosphere. But if the detection of helium can be confirmed, the implications would be profound. "Until now, we had only limited evidence for atmospheres on temperate rocky exoplanets. Demonstrating that LHS 1140 b has retained a substantial atmosphere over billions of years would show that at least some habitable zone Super-Earths around red dwarfs can survive the intense early activity of their host stars."

Linux Desktop Market Share Surpasses 10% in North America

2 août 2026 à 14:04
The blog Linuxiac reports: Linux has crossed a major milestone in North America, with the open-source operating system now accounting for 10.65% of desktop usage in the region, according to Statcounter's latest figures for July 2026. The result places Linux firmly in double-digit territory for the first time in Statcounter's North American desktop operating system statistics. For comparison, Statcounter recorded Linux at 5.52% in June 2026, so the share nearly doubled in one month... However, the sharp monthly increase needs context. Statcounter's June figures included an "Unknown" category that accounted for 9.24% of North American desktop usage. Its reduction seems to have coincided with Linux's rise, possibly indicating better identification of previously unclassified traffic... Statcounter is not the only major web measurement platform showing Linux with a substantial presence on North American desktops. Cloudflare Radar data, filtered to desktop HTTP traffic from North America over the previous 28 days, also places Linux at a notably high level [9.4%]. StatCounter's data also shows Linux with an even larger market share of 11.87% in just the United States — and a 14.73% market share in India. Linux's market share in other world regions: Asia 7.17% Africa 5.71% Europe 5.49% South America 4.35% China 2.12% And here's how the Linux market share in other countries compare to India and the U.S. India 14.73% United States 11.87% Germany 7.24% UK 6.18% Canada 3.83% Australia 3.55% Linux's surge could be due to its use in automation or headless browser workloads, Linuxiac points out. But another possibility is "growing frustration with Windows hardware requirements, advertising, account integration, telemetry, and forced interface changes has pushed some users to explore alternatives..." "For now, the safest conclusion is that Linux has surpassed 10% of measured desktop web usage in North America according to Statcounter, not necessarily 10% of the region's installed desktop computer base."

Are Return-to-Office Mandates Killing Workers' Trust in Workplaces?

2 août 2026 à 11:34
The Hill published the thoughts of Gleb Tsipursky, Ph.D., who serves as the CEO of the future-of-work consultancy Disaster Avoidance Experts: A recent EnhancV survey of 1,000 full-time U.S. workers subject to new or stricter return-to-office policies found that 72% suspect these mandates are really a voluntary attrition strategy — a strategy by their own employers to make them quit their jobs. A full 46% admit to the practice of coffee-badging. Thirty-six percent have applied for a new job while sitting at their current office desk. Thirty-six percent have started a side hustle since the mandate was announced, in anticipation of being let go or quitting. Those numbers do not prove that employees reject collaboration. They show that many employees no longer trust the official story... The central mistake in many in-office mandates is the assumption that proximity automatically produces commitment. It does not. A worker who spends two hours commuting to sit on video calls with colleagues in other cities is not experiencing culture. That worker is experiencing theater. When executives describe the office as a cure-all, many employees experience lost time, higher costs and lower autonomy. The policy's defining feature becomes its credibility gap. Research keeps undercutting the belief that more office time automatically means better performance. A University of Pittsburgh analysis of S&P 500 firms found that return-to-office mandates reduced employee satisfaction without improving firm performance or firm value.... Baylor University's reporting on office mandates and brain drain found that firms with mandates faced greater turnover among women, senior employees, managers and high-skilled workers, while job vacancy duration increased and hiring rates declined. In other words, the people with the most options are often the first to leave. The employees who remain may not be the most committed — they may simply be the least mobile... Attendance can be mandated, but commitment cannot. When leaders confuse the two, they do not rebuild workplace culture. They create a room full of people planning their exit.
